I wonder what the actual attack vectors here were. Was there actually a hack into binance systems, or was it just some insider or credential leak?
Not saying this is the case, but the way this unfolded, and announcement reminded me of the crypto scams that were popular a few years ago (ponzy schemes), with the final rug-pull being "oh no, our platform was hacked, all your funds were lost, sorry!", i.e. "coscoin"[0][1] I know this is not the case here, but the way they announce the hack is funnily similar to how those fake platforms did their final announcement.
Crazy thought, but what if they went via the Claude Code trojan?
Probably a hack, or at least some spearphishing. You can buy a lot of 0days when your budget is billions.
according to Binance's own account so far, the first statement said it “may involve a compromised DevOps engineer’s laptop” that gave the attacker access to a service container to submit withdrawals. then on Friday, Richard Teng said the attacker “did not simply use one engineer’s permissions”, that they’d found additional points of breach, and malware built to destroy itself and its traces.
they also say there’s no evidence any private key leaked yet their own signing system signed the transfers.
